EMERGENCY SAFETY ALERT
Lithium Battery Fires
Lithium batteries are becoming very popular for powering the control and power systems in our models. This is true because of their very high energy density (amp-hrs/wt. ratio) compared to NiCads or other batteries. With high energy comes increased risk in their use. The, principal, risk is FIRE which can result from improper charging, crash damage, or shorting the batteries. All vendors of these batteries warn their customers of this danger and recommend extreme caution in their use. In spite of this many fires have occurred as a result of the use of Lithium Polymer batteries, resulting in loss of models, automobiles, and other property. Homes and garages and workshops have also burned. A lithium battery fire is very hot (several thousand degrees) and is an excellent initiator for ancillary (resulting) fires. Fire occurs due to contact between Lithium and oxygen in the air. It does not need any other source of ignition, or fuel to start, and burns almost explosively.
These batteries must be used in a manner that precludes ancillary fire. The following is recommended:
1) Store, and charge, in a fireproof container; never in your model.
2) Charge in a protected area devoid of combustibles. Always stand watch over the charging process. Never leave the charging process unattended.
3) In the event of damage from crashes, etc, carefully remove to a safe place for at least a half hour to observe. Physically damaged cells could erupt into flame, and, after sufficient time to ensure safety, should be discarded in accordance with the instructions which came with the batteries. Never attempt to charge a cell with physical damage, regardless of how slight.
4) Always use chargers designed for the specific purpose, preferably having a fixed setting for your particular pack. Many fires occur in using selectable/adjustable chargers improperly set. Never attempt to charge Lithium cells with a charger which is not, specifically, designed for charging Lithium cells. Never use chargers designed for Nickel Cadmium batteries.
5) Use charging systems that monitor and control the charge state of each cell in the pack. Unbalanced cells can lead to disaster if it permits overcharge of a single cell in the pack. If the batteries show any sign of swelling, discontinue charging, and remove them to a safe place outside as they could erupt into flames.
6 )Most important: NEVER PLUG IN A BATTERY AND LEAVE IT TO CHARGE UNATTENDED OVERNIGHT. Serious fires have resulted from this practice.
7) Do not attempt to make your own battery packs from individual cells.
These batteries CANNOT be handled and charged casually such as has been the practice for years with other types of batteries. The consequence of this practice can be very serious resulting in major property damage and/ or personal harm

Lipo Fire Incidents by Cause
Posts that have referenced a lipo cell catching fire have been categorized as to failure cause. This list most certainly does not contain all the incidents and a statistical analysis would be meaningless.

CONCLUSION:
Yo, desde luego, no quiero ser alarmista, pero…… “algo tiene el agua cuando la bendicen”.
Y, ¿Porqué darán tantas precauciones a tener en cuenta, si resulta que no tienen peligro?.
Que conste, que yo no pongo nada de mi cosecha, lo único que he hecho es un pequeño recorrido por la red, y visto lo visto, que cada uno se aplique la “cataplasma” donde le duela.
También quiero decir que soy usuario de lipos, y de momento, sin ningún problema, pero no por eso, me creo vacunado contra cualquier problema.
Seguramente…… ¡ESTAN TODOS LOCOS!, y no saben lo que dicen, o exageran, o es que lo han soñado, o les gusta asustar.

Más o menos lo que dice Gonzo, en su página, sobre el cuidado de las lipos:
http://www.rcmaterial.com/LipoManualES.htm
En un post antiguo, Esco dice:
Dando a entender que “NO PASA NADA” aunque reconociendo implícitamente, y entre lineas, que “hay que andarse con cuidado”. ¿Quién no se ha equivocado alguna vez al programar la carga en un cargador?Es imprescindible cargar las baterías con un cargador específico para lipo, es importantísimo equilibrar los elementos de tanto en tanto, sin perder el sueño. Cualquier descuido en estos sentidos se va a traducir en falta de rendimiento, de mucho a todo. Solo hay dos formas de hacerlas explotar y arder.
1ª- El cortocircuito, estas baterías no tienen memoria, la razón es que su resistencia interna es insignificante, cuando se produce un cortocircuito y hasta que empiezan a tener limitaciones de corriente químicas, la corriente que son capaces de dar son INMENSAS, incendio garantizado.
2ª- Cargarlas totalmente pasadas de tensión y de corriente, tensión entorno a 5V por elemento y corriente sobrada para que no se limite, en este caso cuando se inflan lo hacen con un tiempo suficiente para reaccionar.
Por lo demás, desilusión porque había preparado todo para ver como explotaban pero no es nada fácil, le preguntare a lo guiris como lo hicieron.
Weterlin, un conocido participante en nuestro foro, dice en otro post:
Aquí tenéis una peli con algunas recomendaciones. Evidentemente el incendio está provocado a posta, pero………,las recomendaciones son las de siempre, por algo será.Por esas fechas me llegó un nuevo pack 3S de KOKAM 910 de descarga constante 15C para mi Piccolo. Pack ya montado. Lo preparé para el uso. Volé con él 2 veces, unos 10 minutos en total. Marché para casa. Lo guardé en mi pote ignífugo por si....
Al día siguiente lo cojo para recargarlo. Aparentemente el pack estaba perfecto. Ni la más mínima sensación de hinchado ni nada similar. Cuando lo tengo en la mano sin saber por qué lanza un fogonazo con un humo intenso como si de un cohete se tratase y con un olor intenso que me dejo casi grogui. Tiré el pack rapidamente y dejó de humear.
El pack tenía una de las conexiones quemadas, una esquina. Nada hinchado. Así siguió 10 días al cabo de los cuales comenzó a inflarse un núcleo. Lo he desechado en su totalidad.
Con esta experiencia entendereis que dejase de lado un BOMBA como la que preparaba para el Mikado. Me he hecho con un pack NiMh Sanyo 3600 de 20 núcleos. Me encuentro confiado con él. Vuela menos tiempo pero me encuentro seguro que eso para mi vale TODO.
Tuve mala suerte....? Es posible. Pero de momento no quiero tentarla más. Las Li-pos que utilizamos han nacido para usos industriales, no para el hobby, y así lo indican sus fabricantes en las indicaciones de las baterías. Espero que pronto mejoren la seguridad en estas fantásticas baterías, vistas desde la potencia que entregan.

CONCLUSION:
Yo, desde luego, no quiero ser alarmista, pero…… “algo tiene el agua cuando la bendicen”.
Y, ¿Porqué darán tantas precauciones a tener en cuenta, si resulta que no tienen peligro?.
Que conste, que yo no pongo nada de mi cosecha, lo único que he hecho es un pequeño recorrido por la red, y visto lo visto, que cada uno se aplique la “cataplasma” donde le duela.
También quiero decir que soy usuario de lipos, y de momento, sin ningún problema, pero no por eso, me creo vacunado contra cualquier problema.
Seguramente…… ¡ESTAN TODOS LOCOS!, y no saben lo que dicen, o exageran, o es que lo han soñado, o les gusta asustar.
Un saludo
